Charts in text mode reports

[DagmaraGa]

Hi, I've created the report with calculating grouping in text mode, which pulls as well Custom Data field. Report works perfect (screenshot 1). But unfortunately I can't create a chart for it. Is it because is too much text mode ? I've tried move grouping about, but it's always the same issue. Getting an error and all report getting broken as soon as i'm trying o create some chart. Screenshot 2 and 3 shows what happens with a chart.

You can't chart on a calculated field. You can put pretty much the same formula into a custom data field and then chart on that. You can even add a section break configured so that only admins can see it if you don't want messy calculations displayed all over the place.
